Standard Configuration
- Host:A10CL
- Residual chlorine electrode: TS-238-10M
- Electrode flow channel: PP-86
Core Highlights
- Its wide range and high accuracy allow it to measure chlorine levels between 0 and 20.00 ppm with an accuracy of ± 0.01 ppm. It can detect both high and low amounts of residual chlorine for a full day.
- Multi-temperature compensation adaptation: PT1000 and NTC10K include both manual and automatic temperature compensation from 0 to 100 °C, as well as exceptional situational flexibility.
- Because of the 4-20mA output’s exceptional interference resistance, communication in industrial settings is guaranteed.
- Flexible expansion configuration: Depending on how the system is docked, you can select RS485 or two sets of signal outputs from the base model.
Featured Applications
- Wastewater treatment plant: monitoring residual chlorine levels in the disinfection tank’s intake and outflow and a dosing system to ensure water quality.
- Municipal water supply: Testing the water plant’s effluent and pipe residual chlorine to ensure safe drinking and delivery.
- Pharmaceutical and food industries: Monitor chlorine levels in industrial process water, maintain hygiene, and ensure product quality.
- Chemical and power industries: Monitor the chlorine content in industrial circulating water and the temperature of cooling water to prevent equipment rusting and manufacturing interruptions.
- Large swimming pools and commercial water purification systems measure residual chlorine to ensure water safety.
Daily maintenance and precautions
Installation and usage precautions
- Installation: Use a panel with a 92 × 92mm opening to prevent exposure to extreme temperatures, humidity, corrosive conditions, and direct sunlight.
- Electrode installation: The electrode is fixed with PG13.5 threads, and when used with a flow channel, the inlet and outlet water pipelines must be unobstructed (compatible with 9.5mm pipes).Signal transmission requires special cables that cannot be replaced with ordinary wires.
- Wiring: To reduce interference from dosing and mixers, use a separate power source. When the instrument interface is hooked up to other devices, it needs to be protected by a relay that can handle current.
- For slope calibration, a steady water sample is injected for 15 minutes and modified according to laboratory results. Zero calibration requires pure water without chlorine.Electrodes must be cleaned and wiped dry before calibration to ensure membrane cleanliness.
- The default password is 0000. To prevent non-professionals from mistakenly operating important parameters, update the password after use.
Key daily maintenance points
- Instrument maintenance: Regularly clean the instrument casing to avoid contact with organic solvents such as toluene and xylene; Before long-term use, it is necessary to restore the factory settings and cut off the power, and store it properly.
- Electrode maintenance: The electrode needs to be regularly cleaned of the membrane to avoid contamination affecting the measurement; The electrolyte should be replaced regularly (according to the usage frequency of 2 weeks to 2 months), and the membrane should be replaced promptly if it is damaged.
- Calibration cycle: It is recommended to perform zero point and slope calibration once a month. For scenarios with large temperature fluctuations or complex water quality, it can be shortened to once every two weeks.
- Whether the signal output isn’t normal, check to see whether the cable is broken or the wiring is loose. Before recording data drift, make sure to calibrate or check the status of the electrode.
